[2] It is an intestinal parasite of the turbot (Scophthalmus maximus) and can cause outbreaks of disease in farmed fish.

This parasite was first described in 2002 by Palenzuela, Redondo & Alvarez-Pellitero using material obtained from the gut of a turbot (Scophthalmus maximus).

After examination with light and electron microscopy, and by comparing its ribosomal DNA with that of similar myxozoan species, it was established that this species was closely related to Myxidium leei, another enteric parasite of marine fish, but not to other members of the genus Myxidium.

The parasites can also be found in the heart, muscular tissue and other organs, suggesting that there are other means of transmission through the body, including transport via the vascular system.

[3] The condition causes wasting, with muscle atrophy and fatigue; it is very virulent, there is no known treatment and the mortality rate is high.
